15 Claims. (01. IO-16) This invention relates to escutcheon plates fordoor locks and the like, and especially to adjustable escutcheon plateswith means for looking them in adjusted position and for indicatingtheir position.

Lock hardware and especially door locks and latches as applied to doorsare practically ail provided with inner and outer escutcheon plateswhich function, first, as a, means to secure the 0 look mechanism in adoor; and secondly, as an ornamentation. These plates are usuallysecured to a door by means of screws which extend through the plates andinto the wood of the door or into the lock housing. It is obvious thatthis method of securing the plates is undesirable when the outer platesare considered as the mere removal of the screws,-for instance by aburglar, makes opening of the door from the outside acomparativelysimple matter. Again where locks of this character are installed inmetal doors ordinary screw fastening means are out of the question.

In view of the above, different methods of securing the outer escutcheonplate have been developed, one method being disclosed in my formerPatent Number 1,674,841 filed August 20, 1923, in which the outerescutcheon plate is permanently attached or secured to the lock housingwhile the lock housing in turn is secured in the door by means of aninner clamping plate. A second method is disclosed in my co-pendingapplication, Serial Number 239,389 filed December 12, 1927. 'The'cuterescutcheon plate employed in that instance is adjustable. 35 A threadedconnection is formed lock housing. The inner face of the plate isprovided with teeth and these teeth become embedded in the outer surfaceof the'door when the lock is installed in the door.

in-wooden doors but they are out of theque'stion when metal doors ormetal face doors are considered.

The present application is particularly concerned with adjustableescutcheon plates, the object of the invention being .to providean'adjustable'escut cheon plate for the outer face of a door which maybe applied to either wooden or metal -doors;-to provide means forlocking the outer escutcheon plate with relation to .the lock housing;and i-urther, to provide an adjustment indicator. j

The invention is shown by way of illustrationin the accompanyingdrawings, in which between the escutcheon plate and a projecting hub onthe V g i This fmethod is fairly satisfactory where installations aremade Fig. 1 is a sect ional view of a door showing the manner ofsecuring the outer escutcheon plate,

Referring to the drawings in detail and par- I ticularly Figs. 1 and 2',A indicates a door in which is drilled or bored two holes indicated at Band C. The hole B is bored through the face of the door and housinggenerally is adapted to receive a lock indicated at 2, while the'hole'C' is drilled through the edge of the door at right angles'to the holeB; the hole C being provided for the reception of .a belt or latchhousing such as indicated at 3. "The housings 2 and 3 are in actualpractice interlocked but as this feature forms no part of the presentinvention specific illustration thereof has not been resorted to.

The housing 2' is, in this instance, provided with two hub-likeextensions one at each end thereof as'indicated at i and 5, these hubsbeing provided for the reception of spindles, and knobs whereby a latchor bolt actuating mechanism contained within the housing 2 is operated.The.

hubs .4 and 5 also serve as supports for escutcheon plates generallyindicated at 6 and 7, the plate '7 being slidabl'y mounted on thehub 5while a threaded connection 6a is formed between the plate 6 and the hub41,

The plate '7 wiIlhereinafterbe referredto as the inner escut'cheon plateand theplate 6 as the outer escutcheo'n plate, and as both areadjustable 2 with relation to and with relation itfiis possible tocenter the housing the opposite faces of the door to the latch housing3, as this should be centrally positioned between the two faces of thedoor.

It must be realizedthat' locks of this character are installed in d oorsof varying thickness and it is for. this reason that adjustable housingsand escutcheon pl justable plates of itiis (essential tha ates aredesirable. Where adthis character are employed, t the outer plate, atleast, be

provided with means for rigidly securing it in the adjusted position,and further, that such means be so located that it cannot be tamperedwith, or in other words reached from the exterior surface of the door.This is accomplished as follows:

Formed on the inner face of the outer escutcheon plate 6 are one or morerecesses such as indicated at 9 and adapted to be projected into one oranother of said recesses is a looking or retaining pin 10. This pin iscarried by the housing 2 as shown in Figs. 1 and 2, and is normallyprojected by means of a spring 11. The recesses 9 are beveled off at oneside as indicated at Sat, hence permitting the escutcheon plate to berotated freely in one direction on the threaded connection 611 whenadjusting the same, but rotation of the plate in the opposite directionwill of course be prevented by the pin as it will engage the plate andsecure it against rotation in the manner of a pawl on a ratchet wheel.Hence preventing removal or tampering with plate 6 from a point exteriorof the door.

Doors usually come in standard sizes and thickness, for instance a 2%;inch door, a 2 inch door, a 1% inch door, etc., these three being thestandard sizes most generally used. In the present instance meansare-provided for setting the plate 6 in the proper position beforeapplying it to the door. This is accomplished by slotting the housing 2as indicated at 12 and providing marks on opposite sides thereof such asshown in Fig. 1. If the end of the pin 10 registers with the 1% inchmark then plate 6 is adjusted so that the housing 2 will be in a centralposition when placed in' a 1% inch door. Similarly, if the end of thepin registers with the 2 inch mark then the housing will assume acentral position with relation to a 2 inch door and so on. Hence it ispossible to properly adjust the plate 6 before the lock is installed.

In actual operation, if a lock of this character is to be installed, thedoor is first measured for thickness. If it is found to be 2 inchesthick, plate 6 is screwed inwardly until the end of the pin registerswith the 2 inch mark, the housing is then inserted through the outerface of the door until the inner face of the plate 6 engages theadjacent face of the door. The second clamping plate is then slippedover the hub 5 and it is there secured by a pair of screws 14 which havethreaded engagement with the housing 2 and as these screws are tightenedboth escutch eon plates are drawn snugly and tightly against theopposite faces of the door. The bolt or latch housing may then beinserted, or in some instances it is inserted prior to the insertion ofthe housing 2, but whenever inserted proper alignment or centralizationbetween the housings 2 and 3 is insured.

InFigs. 1 and 2, a spring actuated pin 10 is relied upon to form aninterlock between the housing and the outer escutcheon plate. In Fig. 3,two pins are employed. These are secured in a hardened steel plate 16which is interposed between the face of the door and the inner face ofthe outer escutcheon plate. The pins project into the housing 2 and areslidable therein and they also project into recesses formed in the innerface of the escutcheon plate and when so positioned form an interlockbetween the housing and the escutcheon plate which prevents rotationthereof and thereby secures it in adjusted position. Furthermore, byemploying a hardened steel plate, danger of opening the lock,

for instance by drilling through the escutcheon plate, is reduced to aminimum.

In Figs. 4 and 5, a modified form of a plate 20 similar to plate 16 isshown. This may be constructed of hardened steel or soft metal asdesired. It is provided with two or more inwardly turned legs 18 whichare adapted to en-- gage the exterior surfaces of the housing 2, thisbeing feasible in some instances particularly where the housing 2 isirregular in shape. The

plate shown in Figs. 4 and 5 is also provided with two lugs such asshown at 19 and these are raised with relation to the plate 20 as shownin Fig. 5 so as to enter recesses or depressions formed in the innerface of the escutcheon plate, such depressions being clearly shown. at19a in Figs. 6 and 7, Fig. 7 showing the application of the plate shownin Figs. 4 and 5. A cheaper type of escutcheon plate as shown in Fig. 6,that is, a built up type consisting of an inner shell 21 and an exterioror finishing shell 22, the recess 19a being formed in theinner face ofthe inner shell by die operation or otherwise.

In conclusion it may be stated that it is evident that an interlock isformed between the outer escutcheon plate and the housing 2 regardlessof whether pins or plates are employed. Where the pinsare employed, asshown in Figs.

1, 2 and 3, the inner ends enterthe lock housing while the outer endsenter recesses formed in the inner face of the escutcheon plate, thusinterlocking the two members, and where plates are employed as shown inFigs. 4 to 7, inclusive, fingers l8 straddle the lock housing while lugs1:9 enter recesses in the inner face of the escutcheon plate therebyforming an interlock between the housing and the plate. In eitherinstance an interlock is formed which is inaccessible from the exteriorsurface of the door and as such cannot be tampered with. r
